Some of it has to do with business practices and contracts and each group jockeying with the others for the best or most lucrative deal. MMA and the UFC you don't see much on ESPN because Dana White shunned them ten or so years ago in a deal they wanted to make with him. Instead the UFC opted to rely on PPV for exposure and putting events on television instead o ESPN. With boxing many of the sanctioning bodies have contracts with stations like HBO or Showtime rather than ESPN for broadcast rights and it has been that way for some time. Meanwhile ESPN has decided to go with focusing on more widely accepted and widely viewed sports like they have among their programming. It is what they essentially started with and brought to the dance and what they continue to rely on to this day to any great degree rather than some of those other sports you mention.

They are both on espn. Not as much as other sports, but they are on. I was just at a boxing match a few weeks ago. I was there to support a young man that I used to coach. He was 6-0 as a professional boxer. It was being taped for ESPN Friday Nights Fights. He is now 7-0. They had some K-1 fights too that night. But they weren't taping for those as they were amateurs. I knew 2 of those fighters too. One didn't get to fight as they guy he was supposed to fight didn't show up. I used to train him too. But sent him to train with a friend of mines because his interest was competing in mma. He still comes to train with us too.

Every sport besides those three are all over the media, why is that. I believe if Ali and Tyson were around today it will be up there. I don't really hear anything or see anything about UFC, MMA, or Boxing on ESPN. Can anyone tell me why? And also tell me will and could it get up there?
